Laptop troubleshooting forum: laptop will not boot hard drive

my hard drive will not boot. I took a working drive out of another laptop and it booted fine so i put the drive that would not boot in the other machine and it booted fine. when swapped back,it still wont boot in original machine. very confussing please help

both computers will boot up fine. computer # 1 boots with hard drive from computer # 2. computer #2 will boot with hard drive from computer # 1. computer # 1 will not boot with its original hard drive that will boot in computer #2. It just gives me a black screen with a blinking cursor. diagnostics say replace hard drive but it works fine in another computer

You didn't tell that this laptop would boot with other drives. Then your problem is solved already. Just use that other drive. Seems easier than using dban to fully erase this one and reinstall the OS on it from the recovery disk, and even that is not guaranteed to lead to a result.
